Hyaloid fossa

Hyaloid Fossa

The Hyaloid Fossa is a small depression located in the anterior part of the vitreous body in the human eye. It is also known as the Patellar Fossa and is the area where the lens of the eye is situated.

Anatomy

The Hyaloid Fossa is a part of the vitreous body, which is a clear gel that fills the space between the lens and the retina. The fossa is a small depression that is designed to accommodate the lens. It is surrounded by the hyaloid canal, which is a narrow channel that runs through the vitreous body.

Function

The primary function of the Hyaloid Fossa is to provide a space for the lens of the eye. This allows the lens to focus light onto the retina, which is crucial for vision. The fossa also helps to maintain the shape and structure of the eye.

Clinical Significance

Abnormalities in the Hyaloid Fossa can lead to various eye conditions. For instance, a persistent hyperplastic primary vitreous (PHPV) is a congenital malformation where the hyaloid artery fails to regress, which can lead to a range of vision problems.
